To all whom t may concern,.- V u Be it known that I, JOAH ELLIS, a subject of the Queen of Great Britain, residing at Cleckheaton, in the county ofYork, England;

have invented new andlusmeful Improvements in the Construction of Bricks and other'Mlded Building Materials, of which the following u is a specication.

The object of my invention is to so construct bricks andother molded or man ufactured building materials as to protect the lime from contact with .the weather and also to break the joints. l

Figure l is a front view of my improved brick or building-block. Fig. 2 is an end View showing the relative positions of twolcourses of such bricks or building-blocks. Fig. is a plan view of a corner brick or block according to this invention, showing parts o f adjoining bricks.A Fig. t show s a corner of three courses of my improved brick'orbuilding-block. Fig. 5 shows myinvention applied to coping. Fig. 6 is a front View of Fig. 5.

I construct, my "bricks (Whether plain `or glazed) and other molded or manufactured building-blocks A1 .with a recess or furrow B around two edges of the face of the said .brick or block, preferably upon the top and` at one end, and a projection or iian ge C around the two opposite edges of the face of the said brick. The projections or anges C are of slightly-greater'depth than the recesses e B to allow for the necessary thickness of mortarD in laying same, the projecting edges C of one brick fitting into the recesses B on the other brick, so breaking the joint'and completely protecting the mortar D,.whichis upon the other part of the brick, from the weather andpreventing its decay, thereby strengthening the building and also presenting an even and smooth face. l

By making the iianges C. project farther from the surfaces of the brick in the plane of its face'than the depth o f the recesses into which they it` the iianges and recesses come neatly together when cement or other binding material D is placed between the bricks, as shown in Fig. 2. Inthis manner the front surface of the wall is smooth and there are no wide or gaping cracks or joints 5o between the flanges and the recesses on the face of the wall.

The flanges and recesses are all of-a small fraction of the thickness of the bricks, and to enable the bricks to be built into dwellings and otherstructures having corners or angles each angle-brick is provided with iianges and recesses at the sides of the two exposed faces containing the exposed angle, the flanges being at one side and the recesses at the other. 6o The corner-bricks have two similar recesses B and one iiange C on each front face and one recess B andl two flanges C on one end face,

When applying my invention to copingblocks A, (se-e" Figs. 5 and 6,) I form a projecting part Ei upon one side and a corresponding recess F upon the other side. This projecting part E fits within the recess F of the adjoining brick or block. The recess be- 7o ing deeper than the projection allows for the i necessary mortar required in xing same. The sides C of the coping also project and rest within the corresponding recesses B in the top layer of bricks. By this means the mortar required forthe sides and bottom of such coping is rentirely protected from the weather and other atmospheric iniiuences.

What I claim as fmy invention, and desire to secure by Letters Patent, isi l; The combination, with building-bricks having recesses B on twoadjacent edges of their front faces and projecting flanges C on theremaining adjacent edges of their front faces, of corner-bricks each provided with two similar recesses B and one flange C on its frontV face, and one recess B and two `iianges C on one of its ends, all the said anges and recesses being a small fraction of the thickness of the bricks and tting closely 9o together, and binding material between the main portions of the bricks, substantially as set forth.
